What is a Purple Sweet Potato?
Believed to have been domesticated in the Americas more than 5,000 years ago, today there are more than 7,000 cultivated varieties of the sweet potato grown around the world from New Zealand, Australia, and the Philippines to Japan, Hawaii, China, and North America.
While most Americans are familiar with the orange flesh of the more common sweet potato, the Purple Sweet Potato, as its name implies, boasts a brilliant, jewel-toned purple interior, making it a popular choice for recipes designed to delight the eyes as much as the taste buds.
The purple color is completely natural, the result of an antioxidant called anthocyanin – the same antioxidant responsible for the color of red cabbage, red wine, and purple cauliflower – and boasts multiple health benefits.
Two of the best known types of these starchy tubers are:
- Okinawan Sweet Potatoes - originated in South America, these are also known as beni imo in Japan and as uala, or the Hawaiian Sweet Potato. They have tan/creamy white skin and a grape/purple flesh.
- Stokes Purple® Sweet Potatoes – introduced and patented by a North Carolina farmer in 2006 and now grown more broadly in similar climates, these have light lavender/gray skins, and deep purple flesh.
Where Does the Purple Sweet Potato Come From?
Evidence of Purple Sweet Potato cultivation can be traced back to the Aztecs, and tales are told of the Spaniards taking the crop to the Philippines in the 1490’s followed by China. It was in the 1600s that these colorful potatoes first appeared in Okinawa, the southern island of Japan, spreading in popularity across the country before making their way to Hawaii.
Today, Hawaii continues to be a major supplier and consumer of the Purple Sweet Potato, matched by the growing popularity of the Stokes Purple®.
What Does Purple Sweet Potato Taste Like?
It depends on the variety, but in general, the purple sweet potato has a nutty, earthy flavor. When used in desserts, it’s irresistibly rich and smooth, with hints of vanilla and malt.

How is Purple Sweet Potato Used?
Purple sweet potatoes can, of course, be used in the same types of dishes as orange and white potatoes – because they tend to be starchier, they’re typically cooked for a bit longer than their traditional counterparts to achieve the same soft, fluffy texture.
Mashed purple sweet potatoes are a great example of how to enjoy them; and this recipe only requires four simple ingredients.

How is a Purple Sweet Potato different from Ube?
Ube and Purple Sweet Potatoes are often mistaken for each other and because the flavors are so similar, they can be easily substituted for one another in recipes. That said, they do have distinct differences: Ube is a starchy vegetable also known as a purple yam. While yams grow on vines, sweet potatoes grow underground. The skin of a Purple Sweet Potato is thin, like an Irish potato, and can be eaten, where Ube has a thick, bark-like skin.read about all of our Core Values here and how they apply both to our very special mochi and all the equally special people on the Mochidoki team.
